ANIMAL FOOD.

ll'o Drawing.

This invention relates to the pre aration of a biscuit suitable for use as a pod for dogs and other animals and partlcularly to a specially shaped biscuit containing vitamines.

Previously biscuits prepared for this purose have been made of materials containing a balanced composition adapted to serve as a complete food for dogs from the stand- 10 point of having sufiicient proteid carbohydrate but no consideration has been given to the vital factors of foods, namely the socalled vitamines in the preparation of the biscuit nor has there been any means taken to preserve the vitamines that may have been present in the biscuit upon storage. Feeding dogs with these vitamine-deficient biscuits without any supplementary foods has led to a diseased condition and in some cases death of'the animal due to scurvy, rickets and the like attributable to the original lack of orsubsequent destruction of the accessory food factors.

In the present invention it is the preferred object to prepare a biscuit which in itself is as nearly as possible a complete food for dogs without the necessity of supplementary feeding to furnish thenecessary health preserving and growth-promot-' ing constituent. Furthermore by means of the present invention a biscuit may be obtained having a coating which is impervious or nearly impervious to the air thereby retarding the oxidation of the so-called vitamines present and in addition fissuring of the biscuit is reduced or in most cases eliminated. The .fissuring is detrimental not only from the standpoint of mechanical perfection of the biscuit but also, due to fissuring, oxidation of the vitamine content of the biscuit is more rapid and complete upon storage.

I have found that a biscuit can be prepared from ingredients which by proper g5- baking treatment will yield a foodstuff for dogs which minimizes the necessity of supplementary feedings. The desired vitamines may be obtained from any suitable source but among other considerations cost of the raw materials must be taken. Rice polishings or rice bran serve as the source of the anti-neuritic vita-mine present in the biscuit while wheat flour which has not been bleached or treated chemically to whiten it contain vitamine B or the baked at 450 F.- for 15 minutes.

growth-promoting food accessory. Other suitable sources of vitamine A and B are vegetables which may or may not have been desiccated. If desiccated however desiccatron must have been carried out under conditions such as not to have injured or destro ed the vitamine content. Protection against scurvy preferably is aided by the use of.milk in the preparation of the biscuit but in this respect supplementary feeding of foods rich in vitamine C or the antiscorbutic vitamine is desirable.

- I have also found that by curving the hiscuit slightly it enables a dog, particularly younger dogs, to handle the biscuit more readily. The curvin of the biscuit may be accomplished by %a PATENT OFFICE. 3

king the biscuit on a curved surface and thisis readily accomplished in the present day continuous bak-' ,mg ovens in use. In the examplesgiven below the parts are by weight. As an example of the present invention'the followparts of wheat flour (middling grade), 109 parts of rice bran, 1% parts of malt syrup, 20 parts of glucose, 1% parts of salt, 100 parts of water, 40 parts of milk. The above materials were mixed to form a stiff dough, shaped by cutting and backed 'ing is given:

on a curved surface at 450 F. for 15 minutes. The biscuit prepared in this manner became hard on standing, had a good surface and showed no signs of fissuring.

A superior form of composition in that it contains a greater quantity of the growthpromoting vitamines is as follows:

100 parts of rice polishings, 100 parts of rice bran, 1%, parts, of malt syrup, 1 4 parts of salt, 20 parts of glucose, 40 parts of milk, 100 parts of water. The above material was mixed to form a stiff dough or paste and The biscuits obtained were somewhat more moist than in the preceding formula and required a somewhat longer time to become dry and hard but the biscuit obtained shows no signs of fissuring and had a good surface.

An example of a somewhat shorter biscuit and one which is richer in vitamines is the following:

100 parts of wheat flour (middling grade), 100 parts of rice bran, 10 parts of cod liver oil, 1% parts of salt, 1% parts of malt extract, 20 parts glucose, 40 parts milk, 10 parts of water. The cod liver oil, milk and water were first mixed and the oil emulsified by rapid beating. The solution was then added to a mixture of the dry in- 'gredients, mixed to form a stiff dough or of the biscuit. tipping biscuit can be aste and baked on a curved surface. The

biscuit obtained had a better texture than either of the above formulas in that it was less moist and somewhat shorter. It dried more rapidly and had a somewhat more 1mvious coating or surface. The odor or 52201 of the cod liver oil added did not detract from the palatability of the biscuit and in fact when the three biscuits were oifered to a dog be selected that containing the cod liver oil as being the most desirable. .As mentioned above the curving of the biscuit, so as to make a tipping-up biscuit so that a dog, particularly a young dog. s enabled to handle the biscuit a great deal more readily, can be accomplished in several ways. One way of accomplishing this in the present-day continuous baking ovens is to have the pans'on which the biscuits are baked made up in a series of curvedsurfaces, length of the biscuit so that the wet dough on being placed upon the pan naturally assumes the sha of the curved surface and is then baked ard when lying in this position. The curve may of course be of any degree but the most desirable curve would be of such a degree as to make the center of the biscuit between one-fourth and onehalf of an inch above the plane of the ends Another way in which a made is by pre-formmg the dough so as to have the ends of the biscuit shaped to form an angle so that by a dog merely treading on the end of the biscuit the opposite end would be raised in the air enabhng the biscuit to be eaten by the dog. The shaped ends could readily be formed in'a suitable mold and baked as inv the forego' A biscuit m-bar form is desirable as the tipping or tilting effect is readily obtained by producing the 'bar in bent or slightly curved shape so that it does not rest firml on the floor. Moreover the bar shape lend: to compactness in packaging. A bar 6 to 8 inches long, 1 to 2 inches in width and about %ths of an inch in thicknes is an appropriate size for full grown dogs. The thickness may be increased or decreased as desired. In general I prefer .the length of the biscuit to be substantially ater than the width. A so-called puppy iscuit may be made about 3 inches in length and 1 inch in width having inch.

As stated the bar form may be produced easily in a form which affords a tilting or tippln efiect. It may be curveduniforml throug out its length or may be made with the curves being proportional to the an the manner indicated above to danger a thickness of perhaps ventilated may be irregular curves. The curvature is preferably along the flat side. Another method an one which is very practical to make is that of a bar bent slightly at the middle but with straight members rather than curving ones. When the apex of this bar is met on the floor the bar may be readilytilted.

The tilting biscuit is es ially desirable when non-fissured as the ab sgnce of fissures makes tooth-hold diflicult and this is compensated for by the tilting efl'ect.

I do not however limit myself herein to a non -fissured biscuit but prefer the latter when the -c position contains added vitamines, that h when a biscuit enriched in vitamines is to be prepared. A composition which does not fissure on baking but affords a lazed hard crust over the entire surface is eneficial .in reserving the vita-mine content as noted a ve.

The bar-shaped biscuit in some cases may be made somewhat in form of a femur bone as set forth in Ellis Patent No. 982,711, with however the improvement of having the face of the biscuit curved or bent at the middle secure an effective tilting action. Thus the rectilinear bar indicated above may have its ends enlarged or knobbed to somewhat resemble a femur while at the same time having a curaribboneoran ar vature resembl bend at the m iifdle or near either end to accomplish the same result.

A product somewhat approximat' the sha of a rib bone and having the t1 ting qu ities of a rib bone forms a part of the present invention. I do not however necessarily. follow the roportions of rib bones as a somewhat thic er or heavier product is less fragile and therefore less likely to break on shipment.

A further feature of my invention is that of drying or curing the baked biscuits. The larger sizes after baking contain a considerable amount of moisture. In this condition if immediately packaged moulding is likely to result. This is especially true in the case of a vitamins-enriched product'within the scope of the resent invention. I therefore referably su ject the baked biscuit to airryin or aginguntil the moisture has evap-' orate to an extent suflicient to overcome from moulding. This may take several days or several weeks depending upon the curing conditions. In dry weather, for exam le during the winter season when the humi ity is low ordinary air-dryin may serve the purpose while under'humi conditions a room artificially heated and well used to advanta e. During the drying operation it is desira le not to heat the biscuit too stron ly but simply to subject them to a gentle eat, say between 30 and 50 C. for a suflici'ent periodto cause gradual Water elimination to a point below in vitamines, having a glazed hard crust which moulding 0r decomposition of vegeand being substantially free from fissures table material does not readily occur. whereby in view of the substantially air im- 1 The biscuits preferably are packed 1n pervious crust, the vitamine content is 5 containers lined with waxed paper. preserved against oxidatlon.
